SPINNING` DOUBLING, AND TWISTING MACHINE.

Specification of Letters Patent.

Patented Sept. 20, 1910.

Original application filed August 3, 1905, Serial No. 272,560. Divided and this application filed October 23, 1909. Serial No. 524,245.

To all fro/wm it may concern:

Be it known that I, SEBASTIAN ZIANI DE FERRANTI, a subject of the King of Great Britain and Ireland, and residing at Grindleford'y near Sheffield, in the county of Derby, England, have invented certain new and useful Improvements in and Relating to Spinning, Doubling, and 'lwisting Machines, of which the following is a specification.

The invention relates generally to improvements in machines for spinning, doubling, twisting and the like operations, referred to generically hereinafter as twisting.

The constituent elements of such machines differ greatly in form, but in those machines in which the twisting is continuous instead of intermittent as in a mule, the following essential elements are present, namely, a rotatable twisting element proper, t'rom which or to which the material to be twisted is transferred, and suitable means generally taking the shape of rolls and hereinafter referred to as threanl-transfer rolls for effecting such transference.

The present invention relates to improvements in thread-transfer devices, the nature of such improvements being described hereinafter and particularly pointed out in the appendant claims.

I will now describe one application by way of example of my invention as applied to a machine having separate units, such as is described in my U. S. Patent No. 927,343, each unit in such specific example including a rotating cup into which the material is spun.

there in the following description and claims I refer to thread I intend this term to cover broadly the material being operated upon, no matter what may be its preoise nature.

Referring to the accompanying drawings: Figure 1 shows an end elevation partly in section of such parts of the complete machine as are necessary for a proper understanding of the present invention, Fig. 2 being a plan of the same, while Fig. 3 shows diagrammatically a method of passing the thread between the transfer rolls, and Fig. t a cross-section upon the line A-B of the movable transfer rolls, while Fig. 5 is a detail of the guide eye, and Figs. 6 and 7 of the thread guides themselves and their mounting.

In carrying the invention into effect according to the form shown, a number of cups, 1411, are mounted in suitable bearings and each cup is inde endently of the others connected by way of the gears, 286, on the shaft, 27, to a conical roll, 178, situated in a suitable trough. The cup, 144, may be supported in suitable air bearings, which consist essentially of al1 accurately turned sleeve, /L, very slightly larger than the equally accurately turned outer surface of the cup, and supported in a sleeve, a', with rubber rings, c', interposed, the sleeve a, itself being finally supported in a suitable housing.

The cup, 144, has mounted upon it a turbine, 125, to which air or other suitable working fluid is supplied in any welleknown manner. A guide, 285, serves to lay the twisted material evenly into the interior of the cup in a well known nnlnner, and as such traverse means forms no part of the present invention, it is not illustrated in the accompanying drawings.

f'ith the roll, 178, a second roll, 178:,

co-acts this second roll being mounted on the end of an arm 161, pivoted at 162, to the trough in which the rolls are disposed. The arm, 161, carries at its free end a socket piece, 159, trunnioned at 160, into the jaws of a fork, a center spindle, 158, rigidly attached to the roll, 178:", fitting into this socket piece. In order to guide the thread to each co-acting pair of rolls, guide arms, 184, having eyes, 179, are provided for each operative unit of the machine. These arms disposed one on each side of any particular roll are attached to a sleeve, 185, this sleeve being' rotatably mounted on a shaft, 180 ruiming along the length of the machine, and connnon to all its units. The shaft, 180, which is held in suitable bearings may be rotated on its axis by means of a quadrant, 181, rigidly attached to it, a worm, 182, gearing with the quadrant and a handwheel, 183.

The sleeves su porting the guide arms, 184, are not rigidly supported on the shaft, 180, but are displaceable in relation thereto, a pin, 184, passing through oppositely disposed slots, 185, in the sleeve, these pins serving as abutmentmembers, and so defining the position of the sleeves, 185, and guide arms carried by them. A spring, 185, serves to hold the sleeves, 185, against the pins 1841*! The method of passing theA thread around the rolls is diagrammatically shown in F ig. 3.

The operation of the device is as follows By actuating the shaft, 180, by means of the liandwvheel, 183, the guide arms are simultaneously removed in relation to the conical rolls, so that a smaller or larger diameter of the same becomes operative, and thereby varies the feed to the spinning cup, or in other words, since the spinning cup is positively geared to the roll, 178, the twist imparted to the material per unit length is simultaneously varied throughout the machine. If, however, the thread breaks, the arms, 184, cooperating with any particular vthread can be independently raised for piecing-up purposes, and will return automatically to their proper position by th-e action of the spring, 185", and the abutment pin, 184,

In the general view of the machine shown in Fig. 1, a doubling process is shown in which three threads are drawn from the bobbins, 284, and are passed by suitable guides to the guide eye, 179, and so through the conical rolls. The threads then pass from the trough in which the rolls are disposed to the traverse guide, 285, the reciprocation of which serves to lay the material evenly within th-e cup, 144, rapid rotation of the latter serving to impart the necessary twist to the material.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is 1. In combination in a twisting machine, conical thread transfer means, guide means for the thread adjustable for varying its position longitudinally of the conical thread transfer means, and means controllable by hand for setting the guide means in different positions along the conical thread transfer means, substantially as described.

2. In combination in a twisting machine, a plurality of thread transfer units, each of said units including conical means, thread guides for said means adjustable to different points longitudinally of the said means, and adjusting means controllable by hand common to the plurality of thread guides for setting the same at different points longitudinally of the conical means to vary the rate of transfer, substantially as described.

3. In combination in a twisting machine, conical thread transfer means, guide means for the thread adjustable for varying its position longitudinally of the conical thread transfer means, and means controllable by hand for setting the guide means in different positions along the conical thread transfer means, said guide means being displaceable independently of the setting means, substantially as described.

4. In combination in a twisting machine, a plurality of thread transfer units, each of said units including conical means, thread. guides for said means adjustable to different points of the said means and adjusting means controllable by hand common to the plurality of thread guides for setting the same at different points longitudinally of the conical means Yto vary the rate of transfer, said guides being individually displaceable independently of the said setting means, substantially as described.

In combination in a twisting machine, a plurality of twisting units, each including motor means and conical thread transfer means serving said unit, the motor means and transfer means of any one of said units being mechanically independent as regards its operative action from the motor means and thread transferring means of any other of said units, guiding means for the thread adjustable longitudinally of the said conical means to vary the rate of transfer, a comm-on member on which the said guides are displaceably mounted, and means controllable by hand for operating the common member to set the thread guides in different positions along the conical means, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
